CAR-H EA'l'ING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 472,689, dated April12, 1892.

Application tiled Tune 15, 1891.

To all whom t may concern.:

Be it known that I, WILLIAM C. BAKER, a citizen of the United States,residing in the city and State ot' New York, have invented anImprovement in Car-Heating Apparatus, of which the following is aspecification.

In car-heating apparatus it has heretofore been usual to provide anexpansion-vessel above the body of the car and into which the pipes fromthe heating apparatus ascend, so that the water circulates through theexpansion-vessel in heating` the car, and there is more or less leakagein the apparatus, in` volving a loss of water that has to be made upfrom time to time by tilling water into such expansion-vessel to keepthe same at the proper height, and a supply-cock has been used with afunnel, usually made of sheet metal and connected by a screw-coupling;but when the supply-funnel is leftin its position for use the same isliable to become charged with cinders and dust.

In my present improvements the supplyfunnel and the screw connecting thesame to the cock are preferably of cast metal and constructed in such amanner that when the funnel is turned up into position for use the screwis tightened, and the cock is made so that the air is allowed to blowoff from the expansion-vessel as the water is introduced, and theair-vent constructed in such a manner'that it can easily be kept freefrom incrustation of salt from the brine made use ot` in the circulatingsystem.

In the drawings, Figure l is a vertical section of the improvement, andFig. 2 is a sectional plan at the line Qc J0.

The expansion-vesselAis ot ordinary character, and the cock B isscrew-threaded at one end and screwed into the expansion-vessel at ornear the water-line of the same, and the plug 2 of the cock is providedwith a square at one end for the reception of awrench, and it also has awater-way 3, so as to be opened or closed, and at the outer end of thecock is a screw-socket 4, receiving the screw-threaded end 5 of thefunnel C, such funnel being, preferably, of metal cast along withthescrewthreaded end 5 of the collar 6, and the parts are constructed insuch a manner that when the collar is screwed up rmly against the end ofthe socket 4 the funnel C will be ver- Serial No. 396,288. CNO model.)

tical and in position for the reception of the water for theexpansion-vessel, and when the water has been filled in through thisfunnel the attendant simply gives the funnel a halfrotation, partiallyunscrewing the same, and the funnel hangs downwardly and is not liableto become detached and cannot become obstructed by cinders or dust. Thefunnel is indicated in Fig. l by dotted lines in the position when it isout of use. vIn the body of the cock there is a vertical passage-way forthe reception of the upper end of a tube 7, and there is through theplug 2 ot' the cock a passage-Way 8,0pening at the rear end into theinner passage-way of the cock leading into the expansion-vessel, andthese two passages 3 and 8 are opened simultaneously for water to besupplied to the expansion-vessel and closed simultaneously when the plug2 has received a quarter-rotation. By this construction the passage-Way8, opening at an elevated point into the expansion-vessel, allows air topass oft freely as the water is admitted, and should any water orbrine'run out it can be caught in a cup. The tube 7 is easy of accessfor the insertion of a Wire or small rod to remove any salt orobstruction in the same.

I claim as my inventionl. The combination, with the expansionvessel andthe cock having a horizontal screwthreaded socket, of the funnel havingabend and a horizontal screw-threaded connection to the cock, whereby thefunnel is allowed to hang down when partially unscrewed and held tlrmlyby the friction when turned up for use, substantially as specified.

2. The combination, with the expansionvessel and the cock having ahorizontal screwthreaded socket and the air-vent and plug with twopassage-ways, of the funnel having a bend and a horizontalscrew-threaded connection to the cock, whereby the funnel is allowed tohang down when partially unscrewed and held firmly by the friction whenturned up for use, substantially as specitied.

Signed by me this 11th day of June, 1891.
